SPECIFICATION forming part of Letters Patent No. 518,750, dated April24, 1894.

Application filed-July 12, 1893. Serial No. 480,268. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES E. BLUE, of Wheeling, in the county of Ohioand State of West Virginia, have invented certain new and usefulImprovements in Work-Holders; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it pertains to make and useit, ref{ erence being had to the accompanying drawings, which form partof this specification.

My invention relates to an improvement in work holders, and itconsistsin the novel combination and arrangement of parts which will befully described hereinafter and particularly pointed out in the claims.

My invention is especially directed to the provision of a work holderwhich is compact in-its arrangement, convenient and accessible howeverapproached by the operator and which is capable of every adjustmentwhich will aid the operator in executing the work in hand.

Referring to the accompanying drawings: Figure 1, is a side elevation ofmy improved work holder, showing the work table adjusted to one side andat an angle in dotted lines." Fig. 2, is a plan view of the same. Figs.3

and 4, are vertical sectional views, taken at right angles to eachother, of Fig. 2. Fig. 5, is a plan view of the upper portion of thedevice, the work table being removed. Fig. 6, is a view of thedetachable interiorly screw threaded support. Fig. 7, is a plan view ofthe work table, the clamping jaws being removed. Fig. 8, is a detailview of the normally stationary clamping jaw. Y

A designates the base or stand having at its upper end the laterallyprojecting arm A, to which is removably secured the interiorly screwthreaded standard support B, which is split longitudinally as shown atB. Lugs b, are projected from opposite sides of the said split, and thesame are adapted to be drawn together, thereby contracting the vertlcal.screw threaded opening, by means of screw 1). The object of thisarrangement is to bind the screw threaded standard 0 which is adjustable in the said support, after having been turned to the properposition, so that the same will not turn or yield in any way to pressureexerted upon it through the medium of the work table, presently to beexplained.

. D is a vertically slotted head having sockets D upon its lower endwhich fit down over the upper end of standard 0 to which it is fixedlysecured'by set screw d. Journaled concentrically in the slot of the headis the segmental projection E, depending from the annular recessedsupport F. Projection E, together with support F, are held in averticalposition or at any angle thereto, by means of set screw Hextendinginward through projecting portion G of head D.

One side of support F is slit vertically as shown in Fig. 5, andprojecting from opposite sides thereof are lugs f, which are adapted tobe drawn together, thus contracting the recess in the support by meansof screw g, projected therefrom and operated by a movable vise handle-g.

I designates the table or work holder proper,

and depending from its under side is the annular boss J having theperipheral groove J, which is engaged by screws j, projecting throughsupport F and by this means the said boss while free to revolve in therecess of the support is held from vertical displacement.

When the table or work holder has been adjusted to the desired angle thescrew g, is tightened thereby contracting the slit in head F, andbinding bossJ sufficiently to prevent the same from radial movement.

The top surface of table I is provided with a transverse depression L,at the bottom of which are the vertical slots M and N, which communicatewith a corresponding transverse recess Z, on the .under side of thetable. Extending ,longitudinally in slot M is screw shaft 0 whichreciprocates head P therein, while movable in slot N, is head P. Slots Mand N are narrower than depressions L, l, and the said heads, beingformed with enlarged upper and lower ends to correspond with saiddepressions while enabled to reciprocate freely through the slot, yet.are held positively from vertical movement. Removably secured to head I"is jaw Q, from which depends stud Q which is adapted to engage one of aseries of openings q, arranged adjacent the edge of recess N, and bythis means the said jaw is held at any desired distance from the centerof the table. Head P carries a correspondingly formed jaw and is in linewith and is adjustable to and from jaw Q as is apparent. The enlargedupper ends of head M, N are the same depth as the recess L, so that theprojecting surfaces of the jaws rest and move upon the top surface ofthe table. The opposite sides of table I are provided with the inwardcuts 1', for the purpose of afiording the operator more convenientaccess to portions of the work he may have in hand. Support Bisprojected a short distance above lateral arm A, and formed around thisprojecting portion is the groove R, and adapted to turn therein is thearm S made in longitudinal sections, as shown, and upon the outer end ofthis arm is supported the revoluble tool box T.

By means of the construction herein shown and described it will be seenthat the work table is afforded every possible adjustment with devicesfor holding the same in whatever position it may be turned.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-

1. An improved work holder comprising a support, an annular clampingband upon its upper end, a table, and a boss depending therefrom whichextends into the said annular clamp, substantially as shown anddescribed.

2. An improved work holder comprising a table having transversedepressions upon its upper and lower sides, a vertical slot connectingthe depressions, heads movable in the slot and enlarged at theiropposite ends to fit the depressions, clamping jaws carried by theheads, and a means for adjusting one or both of them substantially asshown and described.

3. An improved work holder comprising a table having a transverse slot,a head movable therein, a jaw removably secured to the head andprojecting over the table, a stud depending from the jaw which engagesone of a series of openings in the top surface of the table, and asecond jaw adjustable in relation with the first named jaw,substantially as shown and described.

4:- An improved work holder comprising a table having depressions in itsupper and lower sides, the said depressions being connected by two slotswhich are in line, a head movable in each slot, which heads are enlargedlaterally at their respective ends to fit the recesses of the support,jaws carried by the heads, a means for. holding one of the heads rigidwith the support or table, and a screw extending longitudinally throughthe other head for adjusting it, substantially as shown and described.

5. An improved work holder comprisinga table having inwardly extendingcuts 1 upon opposite sides, and dogs adj ustable in a line substantiallyat right angles and adjacent to the line of said cuts, substantially asshown and described.

6. An improved work holder comprising a base, a vertically recessedsupport secured thereto which support is slit vertically upon one side,a means for contracting the edges of the said slit, a standard movablevertically in said support, and a work holding device carried by saidstandard, substantially as shown and described.

7. An improved work holder comprising a base, a vertically recessedsupport secured thereto, standard movable in the support and a workholding device upon the upper end of the standard, and a projection uponthe upper end of the said support having an annular groove, and a toolbox support clamped in said groove in which it is adapted to turn,substantially as shown and described.

In testimony whereof I affix my signature in presence of two witnesses.
